help with an old flash

i have i nikon sb-e flash, could i use it on a canon rebel without damaging the camera?

 

99.999% sure that you could.
I worked with a guy who uses sb800 on canon 40D. no problems there

 

the problem is the flash is really old and if the voltages are different i could mess up my camera

 

Ok, here's a crazy piece of advise, if you don't get the answer here. Call B&H - bhphotovideo.com and/or Adorama - adorama.com (get numbers from their sites), ask their photo staff exactly the same Q.
You can also call Canon regarding that. I've been happy with Nikon's tech support and heard great things about Canon's.

 

Well if you know the problem then why not just google it?

"Nikon sb-e voltage" turns up the very top result that said 30V.

I wouldn't put that on a modern SLR.
